Let me attempt to answer this... What is wrong in this diagram? 173o The data date must be accurately between weeks.o AC cannot be higher than PV when EV is lower.o EV cannot be assessed beyond the data date.o PV cannot be assessed beyond the data date.

Again, I eliminated the very wrong answers. I chose CEV is a measurement of past/present performance at a given point (data date); and not the future. As the graph suggest, it shows that EV is provided in the future. The graph should have stopped at data point.
